Hello,

i have one ecore with enums (states) and a other ecore uses the 1st ecore

so the enum in 1st ecore file is e.g.

State implements Enumerator

ACTIVE(0, "ACTIVE", "ACTIVE"),
INACTIVE(1, "INACTIVE", "INACTIVE");

the 2nd ecore file is e.g.

public class AImpl extends EObjectImpl implements A

State state;

Now i can save A, but i cannot load it:

public void saveModelWorks()
{
Resource resource = createResource();

A a = ...
a.setState(State.ACTIVE)
resource.getContents().add(a);
try
{
resource.save(Collections.EMPTY_MAP);
}
catch (IOException e)
{

}
}

public Master loadModelDoesntWork()
{
Resource resource = createResource();
try
{
resource.load(Collections.EMPTY_MAP);
}
catch (IOException e)
{
LOGGER.error("Error loading", e);
}

}
private Resource createResource()
{

final ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getPackageRegistry()
.put(StateModelPackage.eNS_URI, StateModelPackage.eINSTANCE);

resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap()
.put("binary", new ResourceFactoryImpl()
{
@Override
public Resource createResource(URI uri)
{
return new BinaryResourceImpl(uri);
}
});

return resourceSet.createResource(URI.createFileURI("bla.binary"));
}

java.lang.IllegalArgumentException: The value 'ACTIVE' is invalid.
at org.eclipse.emf.ecore.impl.EFactoryImpl.createFromString(EFactoryImpl.java:471)
at AFactoryImpl.createEnumFromString(ModelFactoryImpl.java:227)

So what could i do?

Thanks

Do you have an EDataType/EEnum called "Enum"? The method name
createEnumFromString appears to imply that's the case...
